A Fort Peck man is set to plead guilty to four counts of burglary stemming from reported break-ins at the tribal law building and jail's evidence room last September.

Mikkel Derrick Shields, 33, was indicted in January on four burglary charges in U.S. District Court. In a plea agreement signed by Shields in February, he agrees to plead guilty to one count.

A change of plea hearing has been set for March 14 in federal court in Great Falls.

Prosecutors allege in the indictment that Shields broke into and committed theft at the Tribal Law and Justice Building four times in September. He is also accused of breaking into the Fort Peck Tribal Jail and stealing items from the evidence room, although court documents do not describe what items were reported stolen during any of the incidents.

The Billings Gazette reported Sunday that Shields is an officer with the tribal police.

Calls to the tribal law and justice department and jail went unanswered Sunday.

On Feb. 1, Shields signed a document modifying the conditions of his release, agreeing to undergo inpatient and outpatient substance abuse evaluation, therapy and counseling if directed by a pretrial investigator.

Shields' plea agreement came less than two months after he was indicted on Jan. 4.
